' and useful improvements in Door-pening Mechanism for Freight-Cars, of which l dodeclare the following;r to be a full, clear, and exact description. l

The present invention'has for its object to provide a simple and ellectivc construction ofniechanisin whereby the 1n1t1al opening of freight ear doors may be effected, and the invention consists in the lfeatures oi novelty hereinafter described, illustrated 1n the accompanyingl .drawings and particularly pointed ont in the claims at the end oli' this specification. l

Figure 1 is a view in side elevation showing a portion of a freight car door and the left hand front post of the door jamb with my invention a plied thereto, the door beiup;` shown in cosed position. Fig. 2 is a view similar to Fig. 1, but showingthe door partially opened and the parts 1n correspondinglyrshifted position. Fin". 3 1s a 'view in cross-section abovethe door-openking" mechanism and looking' downward.

Fig; 4t is a view similar to Fig. 1, but showing a modified form of the invention. Fig..

5 'is view in cross-section on line 5--5 of Fig. el. Fig. 6 is a vievv similar to Figs. 1 and /Lbut showing; a modified :form of the invention. Fig. isa view in cross section on line 7H? ol Fig. 6.

Freight cars having,r sliding doors are 'ordinarily provided with Wedging means whereby the doors may be 'forced tightly against the door openings as the doors are moved to closed position. These Wedging means frequently s0 tightly hold the doors in closed position that the initial opening oi? `the doors `is effected with difficulty and 'tor this reason erowbars or like instruments are -ojl'ten used to effect the initial opening olf the door with consequent danf `ger ofmarring `the `edge oli the door and the post. But my improved invention, 1-

am enabled to quickly etlect the initial openingr o: the door, so that the door may thereafter be readily moved alongits track from the 'front of the `doorway oi' the ear.4

ln the form koli my invention illustrated in Figs. 1, 2, and 3, of the drawings. l. designates the car doorl and 2 the door post at the 'lett hand side nl the door opening. Upon wall of thc car by means of through bolts 5.,

The outer portion et of the stop plate 4c extends beyond the door post, so as to overlap the door when in closed position, this outer portion la beingr flared or turned outwardly to aid in guiding the door as it reaches its closed position. Upon the door 1 and at a point opposite the stop plate l is mounted a plate 10 having outstanding annular lugs or bosses 11 and 11 projecting from the face thereof. The bosses 11 and 11EL `of the plate 10 are formed with openings (preferably square) through' which pass .the through bolts 12 and 13A that pass also through the door and are provided upon their inner ends with retaining nuts 1&1. Upon the plate 10 is. mounted a sliding member 15 provided preferably with inwardly projecting guiding flanges 16 that overlap the sides of the plate 10. The member 15 is formed with elongated slots 17 and l17f1 through which pass the bosses 11 and 1,1. The boss 11 of the plate 10 passes through a circular opening formed in an operating lever 18 that is pivoted upon the boss 11. A Washer 2O is preferably placed between the head of the bolt 12 and the sliding member 15, and preferably a similar washer 21 is placed between the lever 18 and the head of the bolt 13. The rear portion of the sliding member 15 is shallower than its forward portion and across this sliding member 15 extends the Wall 23. The operating lever 18 will be of convenient length to have its Vlower or handle portion ol? convenient length to be readily mani ulated by the attendant, and the upper or s iorter end of this lever is provided with a cam shaped end 25 adapted to engage With the tra-nsverse wall or projecting partQ of the sliding member 15. When the parts are in, the position shown and the door is closed, the sliding member 15 will be in the retracted position illustrated in Fig. 1, andv ant will graso the handle or lower end of the operating lever 18 and svvin the lever in the direction of the arrow, lig. 1. As the operating le"'" 18 is.thus shifted, the cam shaped cnf oi the operating lever will. .bear againnt tun rear face of the transe sliding membei fiding mambo? to paese @lie stop plaie fi? and m' er l5 is from :shown iii Fig. l o the position fi? lle door 2 will be pried diamine@ labemby releasing he i binding acti-mz of its wedges.

When the operating leve? 18* 1s released, il will return to .the vertical pos1- iion geen in Fig. e, tbe sliding member` V1l being also reuriicd io normal position there Shown,

ln the form of my invention illusirete. in Figsa G and 7 of the drawings, the door post 2 al lle left hand Side of the door opening' in the car boy is shown as provided "with a maell casting 4G secured thereto by bolts 40, this casting l0 having a passage way 4:1 iii which is mouaefl a sliding bolt or i'iiembei is provided at the eml farthest from the riool' with a iieacl 43, and at its oiposte end with a mit or collaia e secured t eret'o.

aPreferably, the casting 40 ifs formed with a recess io receive the nut ois collar 44 .whoa libe sliding bolt or memoai 2 is in the position shown ia Fips. and 7, of the fliawiiigs. To the wall of ille car, adiacent the headed enel of the aliing boli of membei' is pivotsilly mounte the operating leve- 8"5 this lever being preferably pivoted @on a bose projecting outwardly :fiom afplate `5l that is secured to the ear wail by bolts seemed io the adjacent parz of ibo ear wall. A bolt 53 passee glirougli the boss 5G of the plate 5l and through ille adjacent part of the cai' wall anal beween the liead of' this bolt 53, and the operating levee. 15b is interposed a washer 55 that retains the operating lever in position upon time boss 50 of tho ,late 5l. 'liie upper emi of the operating ever i8 is formed with acam sliapcfl portion 25 adapted to engage the licaiiod end 43 of lie Sliding bolty oi iiieiiiboi 42, Upon the elige nui or eoiiai fi-lo'f ibo sliding bolt oi' member is; secured stop plate bgtliis plato 14: being connected lo ille edge of the door omerv eonvenient mamie?. 1 Y

From the foregoing desoription, it will be szw that when the car door is in closed positioa, the .parte wili occupy the ositions seen in Figs. A6 and of the drawings. If new it is desired to eeot the initial opening ofthe car door, the operating lever 18b will be ewun in the direction of the arrow, Fig. 6, t erebv cousin the sliding bolt or member 42 to bear against the stop plate 4" and foi-oe 1he oar door open a slight disunce, as the sliding bolt or member 4:2 is moved inward by the operating lever.
